Teaching Small Language Models to Remember: Giving LLMs a Notebook with Differentiable Neural Computers

"Large models memorize the world in their weights. Small models need a notepad." The Problem: Small Models Forget Facts Large Language Models (LLMs) like GPT-4 are remarkably good at recalling facts — "Delhi is the capital of India," "Einstein developed the theory of relativity" — because they have billions of parameters acting as a massive, compressed knowledge store. The model b...

IPC Pipe vs Unix Socket for a Resident Daemon in Tauri — What I Learned

All tests run on an 8-year-old MacBook Air. When I built Ghost Engine — a resident Swift daemon that handles PDF rendering — I had to decide how Rust talks to it. Two options: stdin/stdout IPC pipe, or a Unix domain socket. I tried both. Here's what actually happened. Option 1: stdin/stdout pipe Simple. Spawn the process with Stdio::piped(), write commands to stdin, read response...

We scanned 1,764 vibe-coded apps. 453 had critical vulnerabilities. Here's what we found beyond Supabase RLS.

We just finished scanning 1,003 vibe-coded apps across Lovable, Bolt, Replit, Vercel, Streamlit, Heroku, and others. The Supabase RLS story is well-documented by now — 7% of Lovable apps and 6% of Bolt apps have tables wide open. But RLS accounted for 183 of our 190 CRITs. The other 7 came from finding classes that are arguably worse. ...

Adaptadores USB 10 GbE con chip RTL8159: $80 y mitad del tamaño Thunderbolt

Durante años, conseguir 10 Gigabit Ethernet en una laptop significaba pagar más de USD 200 por un adaptador Thunderbolt enorme, caliente y con un disipador de aluminio que parecía un radiador. En 2026 eso empezó a cambiar: una nueva generación de adaptadores USB 10 GbE basados en el chip Realtek RTL8159 está llegando al mercado a USD 80, con un tamaño similar al de una memoria USB y temperaturas q...

My bot stopped sending questions the day Egypt turned on Daylight Saving Time

I built a Telegram bot that sends math questions to kids every day at 2:30 PM Egypt time. It had been live for two weeks, running every single day without a problem, questions going out on time, kids answering, streaks building up. Then recently I ran /admin_health in the bot and saw 0 scheduled questions. That's when I knew something was wrong and went digging through the logs. The last successf...

Cost-engineering an "AI Generate" button in a freemium product (from $0.08 to $0.029 per click)

TL;DR My coding-interview prep app has a "Generate Visualization" button. Click it on any algorithm problem and Claude Sonnet 4.5 produces a self-contained interactive widget that teaches it — a sliding-window expanding, a two-pointer racing, a DP table filling cell by cell. (That's what the GIF above is showing.) At naive implementation, each click cost me about $0.08. Workable for Pr...

Claude Skills and SKILL.md for Developers: VS Code, JetBrains, Cursor

Most teams misuse Claude Skills in one of two ways. They either turn SKILL.md into a dumping ground, or they never graduate from giant copy-pasted prompts. Both approaches are sloppy. If you want Skills to work in a real dev workflow, you need to treat them like code and operations logic, not like prompt poetry. Claude Skills are directories anchored by SKILL.md, with optional scripts, reference...

Pause Scripts with 'Press Any Key' in Bash, CMD, PowerShell, and macOS

Batch files and shell scripts often need a short wait so a double-clicked window or installer log stays visible. Windows CMD has a dedicated pause command. Unix shells use read. PowerShell sits in the middle and needs an explicit pattern. This page collects portable snippets and the usual pitfalls (pipes, SSH without TTY, CI). For more shell references, see the Bash cheat sheet and PowerShell c...

AI won’t save a product that was never composable

AI won't save a product that was never composable Most product teams shipping AI right now are following roughly the same playbook. A chat sidebar. A summariser. A copilot panel that can answer questions about whatever's on screen. Each release gets a launch post. Each one tests reasonably well in isolation. And yet, a year in, something is off. The product feels louder, not better. Cus...

I Built a Glossary of LLM Terms That Actually Explains What They Change in Production

When I started building with LLMs, I kept running into terms I didn't fully understand. Quantization, KV cache, top-k sampling, temperature. Every time I looked one up, I got either a textbook definition or a link to a paper. That told me what the term is. It didn't tell me what to do with it. What decision does it affect? What breaks if I ignore it? What tradeoff am I making? So I started keepi...
